excerpt | Two Little Cells

So I told (the doctor) about my hay fever, which used to rage just in summertime but now simmers the year round, and he listened listlessly as though it were a cock and bull story;
and we sat there for a few minutes and neither of us was interested in the other's nose, but after a while he poked a little swab up mine and made a smear on a glass slide and his assistant put it under the microscope and found two cells which delighted him and electrified the whole office, the cells being characteristic of a highly allergic system.
The doctor's manner changed instantly and he was full of the enthusiasm of discovery and was as proud of the two little cells as though they were his own.
